The authors found that 72% of all AEs were related to medications, while a univariate analysis revealed that female sex, type 2 diabetes mellitus and pneumonia were independent predictors that an AE would occur. The study found that while two-thirds of AEs caused only symptoms, 12% led to an emergency department visit, 17% led to readmission to hospital and 3% resulted in death. Previous studies have shown that discharged patients have a high risk of experiencing an adverse event secondary to treatment received in hospital. The authors recommend closer monitoring of patients -- particularly of frail elderly patients -- after discharge from hospital.
In a related commentary, Ross Baker and Peter Norton stress the importance of a smooth transition between hospital-based and community-based care in preventing AEs among patients discharged from hospital.
